Step-by-step explanation:
step 1. if x>3 then the zeroes do not exist.
step 2. Therefore 1/(((1/(x+2))+((1/(x+3))) = (x+2)(x+3)/((x+3)+(x+2))
step 3. Which is (x^2 +5x+6)/(2x+5)
step 4. the answer is b.
Answer:
The vertex (h,k) is (-4,-7).
Step-by-step explanation:
I assume you are looking for the vertex
.
The vertex form of a quadratic is
where the vertex is (h,k) and a tells us if the parabola is open down (if a<0) or up (if a>0). a also tells us if it is stretched or compressed.
Anyways if you compare
to
, you should see that
.
So the vertex (h,k) is (-4,-7).
